Detailed Description
The embodiments of the present invention will be further explained with reference to the drawings.
As shown in fig. 1, 2 and 3, in the embodiment of the mounting fastener for a heat dissipating axial flow fan of the present invention, the mounting fastener is provided with a mounting surface 1, the mounting surface 1 has a set length, two ends of the mounting surface 1 are further respectively provided with a protruding portion 11 protruding to the same side of the mounting surface 1, and the protruding portions 11 are respectively provided with a screw mounting hole 12 corresponding to a mounting hole on one side of a flange of the heat dissipating axial flow fan; the mounting screws of the axial flow fan for heat dissipation pass through the fixing member (for example, the casing of the equipment, etc.) of the axial flow fan and the mounting holes of the flange of the axial flow fan to be fitted with the screw mounting holes 12, that is, the screw mounting holes 12 function as or replace nuts, so that the mounting surface 1 (specifically, the bottom surface of the mounting surface 1) is in contact with the surface of the flange side of the axial flow fan for heat dissipation, and the axial flow fan for heat dissipation is fixed to the fixing member. When the fastener in the embodiment is used, the area is large, and the fastener does not need to be aligned and kept in position like a nut, so that the heat-dissipation axial flow fan is easy to mount and simple to operate when the fastener is used; meanwhile, the larger mounting surface 1 can be tightly attached to the mounting flange of the axial flow heat dissipation fan after being mounted, and due to the lower height of the mounting flange, the mounting flange does not interfere with the main body of the axial flow heat dissipation fan, and the problem that the mounting flange is damaged due to larger local stress caused by smaller sectional area of the nut is solved. Fig. 4 shows the positional relationship of the mounting fastener when it is mounted on the axial-flow heat-dissipating fan in the present embodiment.
In the embodiment, as shown in fig. 1, the mounting fastener further comprises a limiting surface 2 for limiting the position of the flange of the axial flow heat dissipating fan, wherein the limiting surface 2 is bent from the other side of the mounting surface 1 opposite to the side where the protruding part 11 is arranged and extends downwards for a set height; that is, the restricting surface 2 is bent toward the bottom surface (the surface in contact with the mounting flange of the axial-flow radiator fan) of the mounting surface 1. In the present embodiment, the angle between the limiting surface 2 and the mounting surface 1 is 90 degrees, i.e. they are perpendicular to each other. Due to the arrangement of the limiting surface 2, even if the axial flow heat dissipation fan vibrates, the axial flow heat dissipation fan cannot shake left and right as long as the mounting fastener is not loosened, and the vibration of the fan is reduced.
In order to further increase the area of the mounting surface 1 and not to interfere with the main body of the axial heat dissipating fan, the shape of the edge 13 of the mounting surface 1 between the two protrusions 11 is adapted to the shape of the edge of the main body of the axial heat dissipating fan. In the present embodiment, the shape of the edge 13 of the mounting surface 1 between the two protrusions 11 includes a circular arc. See fig. 1 and 2.
In order to enable the fixing screw to be more firmly combined with the mounting fastener in the present embodiment, the screw mounting hole 12 protrudes to a set height from the mounting surface 1 toward a surface of the mounting surface 1 opposite to a contact surface with the flange plate of the axial-flow heat-dissipating fan (i.e., a top surface of the mounting surface 1), and a thread is provided on an inner surface of the screw mounting hole 12 so that the fixing screw can be fitted thereto. In some cases in the present embodiment, the screw mounting hole 12 is formed by forming a burring by punching at a set position of the protruding portion 11 and tapping in the burring. In other cases, the screw mounting hole may be formed by punching a hole in a set position of the projection and riveting a nut of a set height into the resulting hole.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
